Well, I have similar results except I get better performances while
reading/writing with {r,w}size=32k instead of 64, about +20MB/s

The disk itself gets 110MB/s reading and 90MB/s writing locally
on the NFS server.

I naively thought that with a 200MB/s write average I would top wire-speed with
NFS (which I do using dd|nc / nc>file)

Writing via NFS is always slower because even with NFS3 it's
partially synchronous.

Understood. Thanks again for your feedback!
